Gridgen Version 13 Released

Combines Structured and Unstructured Tri/Tet Meshing

Windows NT Port Soon To Follow

FORT WORTH, TX
(1 July 1998) –
Pointwise, Inc.
today began shipping Gridgen Version 13, the latest release of
its software used for grid generation and preprocessing
for computational fluid dynamics and finite element analysis.
This release combines Gridgen's proven structured quadrilateral and
hexahedral gridding, with new automated unstructured triangular and
tetrahedral meshing.

"Version 13 will put Gridgen's ease of use
and high quality grids into
the hands of even more engineers", said John Chawner, Pointwise's
president. "We now have a tightly integrated mesher that
combines the high quality and accuracy of structured grids with the
automation and time-savings of unstructured meshes."

Gridgen's triangular surface mesher saves engineers time
by meshing across one or more trimmed NURB surfaces,
even when there are
gaps and overlaps between the surfaces. This allows an engineer
to begin meshing a CAD geometry without having to spend time cleaning
up dirty geometry.
Gridgen's tetrahedral volume mesher has been developed
in cooperation with
Geometricon, L.L.C, which is headed by Dr. Timothy Baker, a world
recognized expert in unstructured
meshing. Dr. John Steinbrenner, Pointwise's Vice President of
Research and Development notes that "by combining Geometricon's
technical expertise with Pointwise's ability to deliver technology as
a practical tool, the users come out ahead. They get the benefits
of quality meshes that are easy to generate."

Version 13 also adds new diagnostic capabilities that
lets users graphically
examine several grid quality measures in order to assess the
suitability of grids and identify any problem areas.
In addition to being able to display color contours of
grid quality measures, users can enter pass/fail criteria and
Gridgen will indicate the meshes that do not make the grade.

Gridgen is known for its:

interactive interface using OpenGL graphics to run on Unix
workstations from Silicon Graphics, Hewlett Packard, IBM, Digital,
Sun, and coming in the third quarter of 1998, Windows 95 and NT,

geometry modeling tools,
robust IGES import, and fault-tolerant gridding methods that let
analysts work effectively with large and less-than-perfect models,

highly automated and wide variety of gridding
methods that
allow users to create good grids right from the start, and

Pointwise, Inc. is solving the number one problem facing
engineering analysts today: mesh generation for CFD and FEA. They
do this by being a premier supplier of grid generation software and
services centered around the Gridgen software product.
Gridgen software is currently in use at hundreds of sites around
the world including Lockheed Martin, Boeing, Northrop Grumman,
Sandia and Los Alamos National Laboratories, Allison Engine Company,
General Dynamics, NASA, Navy, Army, and Air Force Labs, and Raytheon.

In addition to
developing, supporting, and marketing the Gridgen product family, the
company is involved in numerous research and software development
projects related to numerical grid generation.
